Causes Of Allergy Symptoms

Hay Fever and Allergies Can Lower Student Test Scores

Your body responds too strongly to pollen produced by flowering plants. The pollen is the male reproductive cell of the plant. If you are not allergic, the pollen does not make you sick, but if you are allergic, your body mounts a defensive response.

Brightly colored flowers rarely produce allergy-causing pollens. The problem comes from plants that pollinate using the wind to spread each pollen cell. Large quantities of pollen can be spread on a windy day, sometimes as much as 20 miles.

The troublesome pollens come from junipers, pine trees, all grasses, several varieties of weed and many common deciduous trees those trees whose leaves mature and fall in the autumn.

What Are Colds And Allergies

The common cold is a virus of the upper respiratory system which causes symptoms such as a runny nose, cough, sore throat, and general low-level feelings of unwellness. Typically, toddlers with a cold start to feel better within a couple of weeks.

Allergies are caused when your toddlers immune system overreacts to usually harmless elements, such as pollen, pet dander, mold, and insect bites. Allergy symptoms, such as coughing, sneezing, and a runny nose, range from mild to life-threatening. Allergy symptoms usually continue until you remove the allergen or receive treatment.

Is There A Fever

Allergies can bring on sneezing, watery eyes, itchiness of the eyes, nose, and roof of the mouth, and sometimes a sore throat.

But âyou donât get fever with allergies,â even though they’re often called âhay fever,â says Marc McMorris, MD. He’s a pediatric allergist and immunologist with C.S. Mott Childrenâs Hospital.

âUsually, colds will come on gradually and you get runny nose, itchy eyes, and a low-grade fever .â

Allergies in Children With Fever

Q:Can allergies cause fever in children?

A:Can allergies cause a fever? Generally, no. Sometimes, however, allergy symptoms can make you vulnerable to a bacterial or viral infection. A bacterial or viral infection can lead to a fever, which you can indirectly blame on your allergy.

Some symptoms of an allergic reaction can cause mucus build up in different parts of the childâs body, leading to an infection. The most common secondary infections found in children with allergies are ear infections, sinus infections and bronchitis. Talk with a pediatrician to determine the cause of the fever.

Allergy Treatment

  • A pediatrician will properly diagnose and recommend the most effective treatment.
  • Prevent allergic reactions by identifying the allergens causing the reaction.
  • Avoiding allergens and giving the child a daily antihistamine.

Fever Treatment

  • Treat a fever resulting from allergies with a pain reliever/fever reducer.
  • Do not use aspirin on children under the age of 18 years. Aspirin products may increase the childâs risk of developing Reyeâs Syndrome.
  • Dressing the child in loose-fitting clothing, giving a warm bath and providing plenty of fluids.

Go to see a doctor immediately if a child with allergies shows the following signs: a fever over 105 degrees, constant crying, has a stiff neck, has difficulty waking up, develops purple spots or has difficulty breathing.

While some symptoms of seasonal allergies, such as a runny nose and coughing, mimic those of a cold, fever doesnt occur in allergies. Allergies should never cause a fever in a patient, says Dr. Nick DeBlasio, a pediatrician and medical director of the Pediatric Primary Care Center at Cincinnati Childrens Hospital Medical Center in Cincinnati. If a child has a fever, they likely have either a viral or bacterial infection. I often use the presence of a fever as one way to distinguish between allergies and infection.

Its also important to keep in mind that babies dont typically suffer from hay fever so if theyre congested or generally feel unwell, its doubtful its related to allergies. Its rare for a child to suffer from seasonal allergies under age 2, notes DeBlasio. Unlike food allergies, which can develop any time during a childs first year, children need at least two seasons of exposure to the main culprit behind seasonal allergies pollen in order to have a negative reaction, according to Seattle Childrens Hospital.;
